Failed to return School shoes!

Went in-store to return a pair of shoes. Mind you we bought 3 pairs in December 2025 for Jan 2026. We misplaced our receipt and was told in-store that they cant pull up a statement of a date of purchase even even thou we advised them which month it was purchased. Less than 3 months old and was bought on a Ackermans store card with todays technology you cant print a slip??? What a waste of time and petrol - The manager and staff at Kenilworth were not helpful and claimed their system is "basic" and that no Ackerman's store is able to. Although google says they can!!! ( and by the way the other two pairs are fine and its not like we wanted the credit we wanted to replace it with a more expensive shoe instead! )
